First off, thank you fracas for dropping the link in fleet signal, much appreciated.
I would keep 2.0, but port over the SRS rules, using current SRS stats, let any ship take any SRS, but allow as many tokens as wanted, interceptors allowed only one intercept before returning to base (same for bombers and fighters, if you want to use their PD) and full wings may be launched, again and again, but one less wing for point of damage on the carrier.
Most of the rules cannot be ported without new stats...
